Prairie Sunflower, also known as Maximilian Sunflower, is a native to the Eastern half of North America. This slender perennial herb produces erect stems that may reach 6 to 9 feet tall. The stems are derived from stout rhizomes which were used as a food source by some Native American groups. Prairie Sunflower is drought tolerant once established and may spread so it requires ample space in the landscape. Photos by Laurel Woodley
